Be it'known thatI, l V L-LLIAM F. Cn eisg a citizen of the United; States, re-

and exact description of the invention, such Q as will enable others skilled in the to which it appertains to make and use the same. Thepresent invention relates toa folding or collapsible trough or tray adapted especially for holding a hog or other animal While being operated on, and an objectot lower edges h nged.together,]whereby the the invention is the provisionof such a de vice comprlsing a novel construction whereby the device can be compactly folded or c'llapsed when. not in use, as well as pro-' viding. a serviceable ancletlicientvineans for supporting the animal during the operation, the present invention being an improvement over theconstruction disclosed in my co pending application serial No. 498,6 l5, filed 7 September 6, 1921. v 7

Another object/is the provision of such a device including supporting-legs andbraces for the trough constructed and arranged to fold into compact relation with the trough, and when unfolded and positioned servin to etficientl sn 3 ort the trou h during the operation, or use ofthedevice.

A further object. is the provision of such a device having straps or equivalent means for holding down the animal during the operation, and also adapted for holdin g the device in folded or collapsed position, and

for conveniently carrying same.

With the foregoing and other objects in view, which will be apparent asthe descrip tion proceeds. the invention resides'in the construction and arrangement of parts, as hereinafter described and claimed, it being I understood that changes canbe made within the scope of what is claimed, w1thout de parting frointhe spirit of the invention.

The invention is illustrated in the acco1npanying drawings, wherein 7 Figure l "s a s de elevation of the 1mproved structure.

The]troughor tray cornprises the op'po s te sldes 11, which may be boards or other suitablematerial, andsaid sides. have their sides can be swung api rt'at about a right angle with one anotl1er,' wit'h said'sidesdi verging upwardly, as seenin Figsi' it and 6. The sides can also be swung together; in folding thedevice, as seen in Figs. .5 and 7. The end hinges adjacent to thelends ofthe sides comprise the angularhinge'leaves 12 hingedly connected by the hinge "pins 13, and there are two intermediate hinges'of; similar construction, having thdangular hinge leaves 15; hingedly con'nected by the [hinge pins 15. The h nge leaves are secured to the outer surfaces and loweredges otthe sides 11, with the hinge pinslocated between .thejlower edges. of, said sides. as. clearly seen in Figs. 6 and 7. i

In order to .lirrnt the opening of the 'trough or the separation of the sidesll; a

jointed stay 16 is disposed at the forward end of the trough, and has its ends pivotal'ly engaging bolts 17 carried by the "forward. 7

ends of the sides 11' adjacent to the upper edges of said sides. Said stay Will straighten out when the trough is opened, to. limit the'separation ofthe sides 11', and said stay can bebroken to told, as seen inxF-ig'; with thetrough. V I The trough is provided at itsreanend with ,means for'attaching said end of the trough'to the upper edge or" a wall, fe'nce,' board or other support", Thus, slotted bars 18- slidably engage clamping boltslll) can ried by the sides 11 at the outer'surfa'ces thereof near the upper edges andlrearends I of said side, and said bars: have stems or shanks 2O projecting rearwardly beyond the rear ends of the sides and formed-with depending jaws or hooks 21. *Said stems or shanks can extend over the support, with the jawsor hooks engaging behind said sup-- port, andthe bars 18 can be adjusted for clamping the support between said jaws and rear end of the trough, and by tightening the bolts 18' the trou h is clamoed or sej curedrigidlyto the'support. 1O

TheYbrac es29'have slots31 near their up.- .periends, whereby thefupperends of the front'braces'29 canengage theibolts -17 and 'theupperendsofthe rear braces'29 can en- ;jgagelthe stems or shanks 20, for attaching 7 said upper ends of the braces to the opposite'endsof the sides '11, in order to hold "the trough in proper position when opened. Inclined brace rods 32 havetheir low r terminals inserted through apertures in the stays E27, and the lower ends of the braces, or

bars .29 have apertures. to engage over said ,termlnals of the rods or braces32,;and'nuts .33 are (threaded on the lower terminals of I'said' rods '32, for clamping: the rods 32,

stays 27 andbraces '29 together. This will .make the. supporting;structure rigid, and the rods 32fhave eyes 3 liat their upper ends engaging'dependingeyes 3 5 with which-the hinge pins 15 are-provided. The rods or bracesi32thus brace the legs agalnst longi tudinal swinging movement, 7 and the braces 129- and staysQTbrac-e'the legs and sides of fthetrough laterally. The rods32 are also pivotally anchored: to the intermediate frh-inges, so as tohenablesaidrods to be swung .against the lower edges of the sides 11, when the structure. is folded."

vdifi'erent longitudinal Straps 36 extend transversel across the trough for holdlngdown the legs of the animal, and longitudinal rods 37 have their terminals secured to the outer surfaces of the" sides 11 near the upper edges thereof, whereby the straps can be attached to said rods at trough. Each strap 36has a. buckle or clasp 38 thereon nearone terminal, so that said terminal can be engaged behind and around the cerrespondingrod 37 to form a loop 39 with the termmal engaging saidb-uclrle or clasp.

Eachstrap isalso providedat its-lower or' inner surface with a'longitud'inal series of hoolrs lO to" engage under the opposite rod 37,,and providing means of adjustment in addition-to the buckle or.clasp-38,.whe reby eachstrap can behdra'wnfdowntight for holding the legs of the animal down firmly. Each strap is also provided near the terminalopposi te to the'buckle38 with a longitu-, 'dinal series of apertures 41 for theengage ment of such-terminal with'the buclrle 38 when using the straps 36 for holding the trough in folded position, as will's hereina'iter more fully appear.

Thereis a longitudinal series of members 13 "'rranged in pairs transversely ofthetrough, for the positioning of the head-holding strap 42 at difi'eren't longitudinal positionsf The terminals of the strap 4-2 'can be inserted through and loopedaround the members 43' and engaged with" the'b-uckles or clasps' l l.

23 corresponding parts can be detached or] eliminated, and the rear end of the trough i'asten'edb-y the jaws; or'hool'rs 21 over the upper edge of a fence, -wall,. or other similarisupp'ort. 'llhe'straps 36*are slidable' or adjustable longitudinally" to be disposed properly over" the legs or body of the animal, and the hooks e0 enable the straps to be tightened down and "secured by engaging the respective hooks under the corresponding rods 37.

The rods or braces 32 can then bes'wungfltowar'd one another against the lower edges of the sides 11, and the pairs of legs also swungtoward one another agalnst thelower edges ofjsaid sides 11. This will fold'the. structure within small space, for conveniently carrying, transporting orstoring the device; The straps can be'used for holding the ,ClQVlCG' in folded position and for carrying same. Thus, the straps 36 can be inserted through the members 4 5 and rods as ,seenfin Figs, 2 and 7, and the, terminals which have the apertures a1 can be engaged in the buckles" or clasps 38, whereby s'aidstra 'asembrace the sides and legs ofthe folded structure,t0

The terminals of the strap 42 are then engaged around the straps 36 above the upper edges of the sides 11, as. seen inFig. '2, and are engaged with the .buckles {14, whereby said strap 42 provides a handle or grip for conveniently lifting and carrying the; device. 7 v
